Nonlinear optical properties of poly(aniline-co-pyrrole)@ ZnO-based nanofluid

Abstract

In the current research, poly (aniline-co-pyrrole)@ZnO (PANCP@ZnO) nanocomposite was fabricated via the solvent casting technique. Subsequently, nanofluid based on PANCP @ ZnO was prepared via the two-step process. FTIR, FESEM/EDX, XRD, and TGA analysis were employed for the characterization of the materials. Additionally, UV–Vis spectroscopy employed for studying the optical properties of materials. Nonlinear optical studies were carried out by using the open-aperture and close-aperture Z-scan technique in continuous wave mode at 532nm. The optical properties of PANCP@ZnO nanofluid were changed with varying concentrations and laser intensity. The results showed the PANCP had self-focusing and reverse saturation absorption natures in some intensities and concentrations while the PANCP@ZnO nanofluid had only self-defocusing and reverse saturation absorption natures. Consequently, the PANCP@ZnO nanofluid may be used to protect the eyes and optical instruments against high-intensity laser. Additionally, it is an excellent candidate for use in nonlinear optical device applications.
